The biceps brachii primarily serves to supinate the forearm at the elbow joint. [1] The muscle belly is composed of two heads. The short head is more medial and highlighted in green. The long head is more lateral and highlighted in red. A biceps tendon rupture or bicep tear is a complete or partial rupture of a tendon of the biceps brachii muscle.
It is formed by the longitudinal hollow between the biceps and triceps muscles. The pulse of the brachial artery can be felt in the medial bicipital groove. [1] It should be distinguished from the bicipital groove or intertubercular sulcus, which is not a surface anatomy structure. It is the groove where the long head of biceps tendon runs ...
All of the tests take advantage of the fact that the labrum meets the tendon of the long head of the biceps muscle, and thus will normally produce pain in the region if a tear is present. Additionally, clinicians may order an MRI ( Magnetic Resonance Imaging ) or CT ( Computed Tomography ) scan to be conducted utilizing contrast injections to ...
A SLAP tear or SLAP lesion is an injury to the superior glenoid labrum (fibrocartilaginous rim attached around the margin of the glenoid cavity in the shoulder blade) that initiates in the back of the labrum and stretches toward the front into the attachment point of the long head of the biceps tendon.
The supraglenoid tubercle is a region of the scapula from which the long head of the biceps brachii muscle originates. [1] [2] It is a small, rough projection superior to the glenoid cavity near the base of the coracoid process. The term supraglenoid is from the Latin supra, meaning above, and glenoid, meaning socket or cavity. [3]
The biceps muscle has two heads, the short head and the long head, distinguished according to their origin at the coracoid process and supraglenoid tubercle of the scapula, respectively. [1] From its origin on the glenoid, the long head remains tendinous as it passes through the shoulder joint and through the intertubercular groove of the ...
Biceps femoris tendon rupture can occur when the biceps femoris is injured in sports that require explosive bending of the knee as seen in sprinting.If the athlete is fatigued or has not warmed up properly he/she may suffer a hamstring strain/rupture, which is the tearing of the hamstring muscle.
The supraglenoid tubercle is where for the long head of the biceps brachii muscle originates. It is a small, rough projection superior to the glenoid cavity near the base of the coracoid process . The name supraglenoid tubercle refers to its location above the glenoid cavity.
